Design of mechanical compliance would be one of the most important technical foci in making humanoid robots really interactive with the humans. For safety insurance the mechanical compliance should be developed to humanoid robots. The introduction of the passive compliance to humanoid robots has large possibility to achieve the human skill by using the dynamical energy stored in the compliant m...

Object manipulation techniques in robotics can be categorized in two major groups including manipulation with and without grasp. The aim of this paper is to develop an object manipulation method where in addition to being grasp-less, the manipulation task is done in a passive approach. In this method, linear and angular positions of the object are changed and its manipulation path is controlled...

<p>Solar trackers are support platforms that keep photovoltaic panels facing the sun by following from dusk to dawn. There exist active solar make use of motors and gears orientate towards sun; passive operate through differential heating fluid in tracking rack follow sun. Passive suffer lack a night return mechanism slow wake-up response mornings due limitations on surface inclination an...

The robots are interacting with humans in various aspects. Safety issues are increased in various robot applications. Many robot arms have been introduced for safety. The passive compliance methods have faster and high reliability than active methods. In this paper, a new safety mechanism based on passive compliance is proposed. The variable stiffness joint employed spring and roller is economi...
